Vedclass · Answer

(C) Energy is released in a nuclear process if the total binding energy of the products is greater than the total binding energy of the reactants.From the graph, we identify the mass numbers $(A)$ and binding energy per nucleon $(BE/A)$ for the nuclei:For $W$: $A = 120, BE/A = 7.5 \, MeV \implies 	ext{Total } BE = 120 	imes 7.5 = 900 \, MeV$.For $Y$: $A = 60, BE/A = 8.5 \, MeV \implies 	ext{Total } BE = 60 	imes 8.5 = 510 \, MeV$.Now, let us check option $(c)$: $W 	o 2Y$.Total $BE$ of reactants $= 900 \, MeV$.Total $BE$ of products $= 2 	imes (510) = 1020 \, MeV$.Since the total binding energy of the products $(1020 \, MeV)$ is greater than that of the reactants $(900 \, MeV)$, energy is released in this process.

The binding energy per nucleon versus mass number curve for nuclei is shown in the figure. $W, X, Y$ and $Z$ are four nuclei indicated on the curve. The process that would release energy is
